摘要： The invention includes methods for stimulating a hydrocarbon-bearing formation by perforating a wellbore and introducing an acidic composition in the wellbore. A preferred embodiment includes inserting an isolation plug in the wellbore at a predetermined location followed by inserting a perforating tool and a breakdown acid into the wellbore. The wellbore is perforated by the tool to create a perforated area. The breakdown acid is allowed to come into contact with the perforated area for a predetermined period of time sufficient to prepare the formation for stimulation. The tool is then removed from the wellbore wherein stimulation of the perforated area is thereby initiated. Also disclosed is a corrosion inhibiting composition for use with the acidic composition.

摘要： A method for the stimulation of a hydrocarbon-bearing formation, said method comprising the steps of:
providing a wellbore in need of stimulation;
inserting a plug in the wellbore at a location slightly beyond a predetermined location;
inserting a perforating tool and a spearhead or breakdown acid into the wellbore;
positioning the tool at said predetermined location;
perforating the wellbore with the tool thereby creating a perforated area;
allowing the spearhead acid to come into contact with the perforated area for a predetermined period of time sufficient to prepare the formation for stimulation;
removing the tool form the wellbore; and
initiating the stimulation of the perforated area using a stimulation fluid.
Also disclosed is a corrosion inhibiting composition for us with the acid composition.-
